devm_kstrdup() may return NULL if internal allocation failed. Thus using label, name is unsafe without checking. Therefor in the unlikely case of allocation failure, sx150x_probe() simply returns -ENOMEM. Signed-off-by:

devm_kasprintf() may return NULL on failure of internal allocation thus the assignment to .label is not safe if not checked. On error npcm7xx_gpio_of() returns negative values so -ENOMEM in the (unlikely) failure case of devm_kasprintf() should be fine here. Signed-off-by:

After patch b96eea71 ("pinctrl: fsl: add scu based pinctrl support"), NO_PAD_CTL pads map are not skipped anymore which results in a possible memory corruption. As we actually only need to create config maps for SCU pads and MMIO pads which are not using the default config (a.k.a IMX_NO_PAD_CTL), so let's add a proper check before creating the config maps. And during MMIO pads parsing, we also need update the list_p point as SCU case to ensure the pin data next parsed is correct.

The rk3188 has pins that are not handled through the regular iomuxing for handling either nand-flash or an emmc and are set through only one specifal setting. So utilize the routing function to simply do that setting depending on one of the core nand/emmc signals that are actually regular pins handled through pinctrl. Signed-off-by:

Right now we expect the pin-rounting settings to be in the same area as the iomux setting itself. And while that seems to be true for all newer Rockchip socs, back in the wild west days of old this wasn't true. Nowadays pin settings in the GRF normally stay in the GRF and the same is true for pins configured from PMU registers. But old socs like the rk3188 really sprinkle pin settings somewhat randomly through both for its bank0. Therefore add the option to specify a location for the route setting, so that we can map older socs correctly. We'll keep "same" as the default, so that we only need to specify a location in the corner-cases described above. Signed-off-by:

When attempting to setup up a gpio hog, device probing will repeatedly fail with -EPROBE_DEFERED errors. It is caused by a circular dependency between the gpio and pinctrl frameworks. If the gpio-ranges property is present in device tree, then the gpio framework will handle the gpio pin registration and eliminate the circular dependency. See Christian Lamparter's commit a86caa9b ("pinctrl: msm: fix gpio-hog related boot issues") for a detailed commit message that explains the issue in much more detail. The code comment in this commit came from Christian's commit. I did not test this change against any hardware supported by this particular driver, however I was able to validate this same fix works for pinctrl-spmi-gpio.c using a LG Nexus 5 (hammerhead) phone.
